I have not played with
Thrasios, Triton Hero and don't know if that allows the deck to run well with so few lands. I think i still would recommend to add 1-2 more lands because it always fills bad to miss land drops and not get to play.
With my concern for people playing low amounts of lands.
-
Herald's horn are probably worse than an normal mana rock as it only affects 15 cards in your deck while a mana rock will affect all of your spells and activating
Thrasios, Triton Hero too. With out top deck manipulation than you ar not too likely to get extra draw from
Herald's Horn. So my recommendation for a swap would be any 2 mana rock or
Dragon's hoard.
-
Electrodominance. I don't know that purpose you want it for, if its for a removal spell than you can find better. Don't know what to swap it for as I don't know your intent behind putting it into the deck.
- While
Barbarian class is nice for your 2 dice rolling creatures I still think investing 6 man to get haste is too much and would probably swap it for a 3 mana enchantment that give haste like
Rhythm of the Wild/
fires of yavimaya/
fervor. Still barberian class is not a bad card, you have to think about what you value most from its effects.
-
Neyith of the Dire Hunt. I don't think you will have the time or mana to play out
Neyith of the Dire Hunt, a dragon and pay for
Neyith of the Dire Hunt ability. From my expirence of playing
The Ur-Dragon dragon tribal, people don't like any number of dragons to stay on the table so From my Experience a dragon's expected life time on the table is short.
-
Purphoros, God of the Forge is not a card i think about when you say
fly under the radar. It's har to remove and deals alot of damage by just staying in play. Might not be a red flag card in your playgroup/ people you play with, but I and most people I know starts to focus and deal with players with
Purphoros, God of the Forge on the table. Would maybe swap for a
Scourge of Valkas-
Rashmi, Eternities Crafter. Might be fine, but better if you can play at instant speed. Don't think you should cut it, but it's probably a card that will be cut at a later date when your list get's more tuned.
Some cards i like for the deck would be
Sneak Attack,
Purphoros, Bronze-Blooded,
Defense of the Heart and
Selvala's Stampede to Explosivly deploy a lot of dragons. A tip with
sneak attack effects is that you can activate it at the opponent before you's end step as the trigger for sacrificing the creature is at the beginning of the next end step.
Your deck looks like to me that you have 2 game plans:
Step 1 (for both plans): make a lot of treasures and use that to win (
magda, Brazen Outlaw or just play out things)
Step 2:
- Deploy a lot of dragons and play
Blasphemous Act or
Starstorm with
Wrathful Red Dragon on the table
-
Miirym, Sentinel wyrm/
Lathliss, Dragon Queen with
Dragon tempest/
Terror of the Peaks for a lot of damage.
I also se that you have a way to make infinite colorless mana and
Staff of Domination/
Thrasios, Triton Hero as payout.
All suggestions and comments are just my opinion and it is not wrong to disagree because i don't know your meta, your playstyle or what power level you want from the deck. Just a tip if you want more or better advice is to give us more of the context around the deck like what you like about the deck, what you want it to do, want kinds of deck you play against/ are trying to beat.
Hope some of the suggestions help
